Unitary frame for openings



l. A. BAUM UNITARY FRAME FOR OPENINGS Filed Oct. 19, 1928 Patented Dec. 8, 19731 UNITED STATES ISAAC A. BAUM, OF CI-IIGAGO, ILLINOIS UNITARY FRAME FOR OPENINGS Application led October 19, 1928. Serial No. 313,473.

My invention relates to building construction, and particularly to a novel buck, jamb and plaster terminal constructed and adapted to be installed as a unit.

In order to simplify andcheapen the cost of constructing the frame for wall openings and particularly frames for doors, I have devised and disclose herein, a unitary frame, consisting of parts of the utmost simplicity, adapted to be completed in the shop ready for immediate installation on the ob.

One of the particular objects of the invention is to provide a unitary structure adapted to properly function without the necessity for building up the parts so as to require welding at points where the welding blemish would occur on an exposed surface. Even under the most favorable circumstances, a spo-t weld will result in a blemish on the surface of the metal at the point of the weld, and this blemish cannot be readily effaced without considerable additional labor. In the construction herein disclosed, the only welds of importance are those necessary to join the plaster finish angle to the flange of the channel and this welding operation 0ccurs at a point where both surfaces are concealed. In order to avoid welds that would occur on exposed surfaces of the j amb, I utilize a wall anchor that engages flanges of the channel, and utilize the apertures formed in the flanges by striking out plaster anchors.

The invention will be more readily understood by reference to the drawings, in which Fig. 1 is a sectional View through a structure arranged in accordance with my invention;

Fig. 2 is a similar view showing a slightly modified form of plaster finish member, and

Fig. 3 is a side elevation 0f the construction shown in Fig. 1.

In the drawings, the wall, which may be of tile or other form of masonry, is indicated at 10. The unitary frame element is of generally channel shape, consisting of a web 11, having a stop 12 formed therein, and flanges 13 adapted to encompass the masonry wall and to fit snugly over the edges thereof. The plaster nish member or plaster terminal is of angular form in cross section, having a base flange 14 that is welded to a flange of the channel and a perpendicular flange 15 terminating in a rebent margin 16. It will be noted that the welds by which the plaster finish member is joined to the channel are concealed beneath the plaster. Preferably, I strike out ribbons or loops 17 of metal from the flanges 13, these being arranged in staggered relation and serving to anchor the plaster 18 to the metal surface of the fianges. A wall anchor which may be in the form of a loop 19 of wire, has hooks 20 on its ends that enter the apertures formed by striking out the loops 17.

In the construction of Fig. 2 the parts remain the same, the only change being in the contour of the plaster finish member. In any case, that member has a base flange 21 and aA finish flange 22 which may be of any desired contour.

Other forms and modifications may be made and I do not wish to be limited except as indicated in the appended claims.

I claim:

1. In combination, a frame member of channel shape in cross section, the flanges of which areadapted to encompass a masonry wall, a plaster terminal member on the outside surface of a channel flange near the forward edge thereof, plaster anchors struck out of said channel flange and adapted to anchor plaster applied to the exterior surface of said channel flange as defined by said plaster terminal member, and a wall anchor having a hook adapted to enter an opening formed by striking out one of said plaster anchors.

2. In combination, a frame member of channel shape in cross section, the flanges of which are adapted to encompass a masonry wall, a plaster terminal member on the outside surface of a channel flange near the for- Ward edge thereof, plaster anchors struck out of said channel flange and adapted to anchor plaster applied to the exterior surface of said channel flange as defined by said plaster termina-l member, and a Wire loop havno hooked ends adapted to enter openings ormed by striking out said plaster 10 anchors.

In testimony whereof I have aixed my signature.
